Specification of Letters Patent.

Application filed September 2, 1905. Serial No. 276,850.

provement in Linotype-Machines, of which the following is a specification.

My invention relates to mechanism wherein a series of finger-keys control powerdriven devices for actuating the matrix-releasing escapements of linotype-machines, the ejecting devices of type-setting machines, and similar devices.

The invention consists of aseries of fin ger-keys arranged to control reciprocating toothed bars, which receive motion from a toothed roll, the arrangement being such that the bars are positively advanced and positively disengaged that they may return to their normal positions, as hereinafter more fully explained.

Figures 1 to 5, inclusive, are vertical sections showing the escapement-controlling bar with its actuating-roll, cooperating finger-key, and adjacent parts, the several figures showing the parts in the successive positions which they assume in the course of operation. Fig. 6 is a rear view looking in the direction of the arrow in Figs. 4 and 5. Fig. 7 is a view of an alternative construction.

Referring to the drawings, A represents a horizontal roll provided with longitudinal teeth and driven continuously in the direc tion indicated by the arrow. It will be mounted at its ends in bearings or supports of any suitable character and may receive motion from any suitable source.

B B are a series of upright vertical bars, having their upper ends engaged with and arranged to actuate the matrix-releasing escapements C or other parts, to which motion must be given when the finger-keys are manipulated. The bars B are mounted in guides D D, formed to permit their longitudinal movement and also to permit an edgewise movement at the lower end. Each of the bars is formed with a shoulder 1), arranged to encounter a banking strip or stop 1), whereby the downward movement of the bar is limited. On the forward edge each bar is provided with a series of ratchet-teeth b and below these teeth with a protruding tooth or finger 6 A spring E, connecting each bar B with the main frame, tends to urge the bar downward. Each bar is also connected at one end to a spring F, which tends to draw its end forward in an edgewise direction. At the lower end each bar is formed with a notch b lying between two projections. Opposite each bar there is mounted in the main frame a lever G on a horizontal pivot g. This lever is jointed at its end with a finger-key H, mounted on a pivot it. Each bar B is provided near the lower end with a lateral stud I to cooperate with a laterally-projecting stud or lip J on the main frame, as hereinafter described.

Normally the parts stand in the position shown in Fig. 1, with the bar in its lowermost position and resting against the lever G, which holds it backward against the stress of the spring F out of engagement with the roll A, so that the parts remain at rest. When the forward end of the finger-key H is depressed, it throws the rear end of lever G downward into the slot 6 whereupon the spring F draws the bar B forward until its teeth engage the roller A, as shown in Fig. 2. The roller immediately acts to lift the bar, as shown in Fig. 3, the stud I moving upward past the forward face of the stud J, which will aid in preventing the disengagement of the bar from the roller, although this is not ordinarily necessary. As the bar continues its upward movement its tooth or finger b is brought into engagement with a tooth on the under side of the roll A, as shown in Fig. 3. The action of the roll on the finger forces the bar edgewise to the rear, as shown in Fig. 4, against the stress of spring F, thereby disengaging the teeth of the bar from the roller and permitting the bar to be carried downward to its original position by spring E. During this downward movement the stud I on the bar rides behind the lip J, whereby the teeth of the bar are prevented from reengaging the teeth of the roll. During the rise of the bar the rear end of the lever G, seated in the notch b, is carried positively upward, as shown in Fig. 3, so that the finger-key H is restored positively to its original position without dependence on a spring or on gravity for the purpose. As the bar completes its downward movement its shoulder above the notch b is carried downward opposite the rear end of the lever G, which again acts as in the first instance to hold the bar back out of engagement with the roller.

It will be observed under the above arrequirement in this regard is that the teeth 6 l'or propelling or driving thebar and the tooth b for effecting the disengagement oi the bar shall be arranged to engage the roll on difl'erent sides oi its center, or, in other words, at points where the teeth of the roll are moving in diflerent directionsfor example, moving vertically Where the teeth I) engage and horizontally where the tooth I) engages.

While I prefer to employ the two springs E and IF, it is obvious that a single spring applied in an inclined relation to the bar B, as shown in dotted lines at K, Fig. 5, will serve the double purpose of urging the bar downward and of drawing it into engagement with the roll.

The fingerkey connections may be varied in form and arrangement at will provided only they are adapted to hold the bar B nor mally out of engagement and to release it, so that it may engage when the key is depressed.

While the figures above described show the parts arranged to lift the bars B, it will of course be understood that the position of the teeth may be reversed, as shown in Fig. 7, in which case the driving-roll will serve to draw the bars B downward against the resistance of the returning spring B.

While I have shown and prefer to use a series of teeth on the bars B in connection with a corresponding series of teeth on the roll, it

will oi course be understood that the size and number of the teeth may be varied at will. In some cases a single tooth on the bar B in connection with one, two, or more widelyseparated teeth on the driving-roll will answer all requirements.

What I claim as my invention is 1. In a keyboard mechanism, the combination of a continuously-rotating toothed driving-roll, and a driven bar toothed to engage the roll and receive longitudinal motion therefrom and also toothed to engage the roll and effect the disengagement of the firstnamed tooth.

2-. The combination of a continuously-rotating toothed driving-roll and a bar mounted to move longitudinally and laterally, said bar toothed to engage the roll and to cause the longitudinal movement, and also toothed to engage the roll and to cause the lateral movement.

3. The combination of a continuously-rotating toothed driving-roll, a bar mounted to move longitudinally and laterally and provided with teeth to engage the roll on difierent sides of its center, spring connections tending to draw the bar endwise and toward the roll, a finger-key mechanism acting to hold the bar normally out of engagement with the roll, and means for holding the bar out of engagement during its longitudinal retreat.

4. In a keyboard mechanism, the combination of the toothed roll, .A, a bar, B, provided with actuating-teeth, b and with a disengaging tooth, b, as described, means for throwing the bar into engagement, means for retreating the bar endwise when disengaged, means to hold the bar normally out of engagement, and means to hold it out of engagement while retreating endwise.

5. In combination, the toothed roll, A,the bar, B, having teeth, 5 and. tooth, b spring connections tending to move the bar toward the roll, a spring connection tending to return the bar endwise when disengaged from the roll, means for holding the bar normally out of engagement with the roll, and means to hold it out of engagement while at rest.

6. In a keyboard mechanism, the combination of a toothed roll, a bar moved thereby, and a key to hold the bar normally out of engagement, the bar adapted to restore the key to its normal position.

7. In a keyboard mechanism, the combination of a reciprocating bar, power-driven means for moving the same endwise, a spring to return the bar, and movable means adapted to hold the bar normally out of engagement and to be returned by the bar to its original position.

In testimony whereof I hereunto set my hand, this 31st day of August, 1905, in the presence of two attesting witnesses.

JOHN It. ROGERS.
